> USDT P2P rates and premiums for 29 fiat markets: median Binance P2P and OKX P2P prices (KRW: Bithumb Spot) compared with a USD reference rate, sampled every 30 minutes (UTC). Six languages: zh-cn, en, ko, vi, ar, es.

Premium = (quoted price / USD reference rate - 1) x 100. Premiums are reference comparisons, not profits, and the USD reference is not a local cash or black-market rate. Samples are taken every 30 minutes (UTC). These public guides describe the website and its open data (CC BY 4.0, cite "coinpay.hk"); check the live pages for current quotes.
